Water purification system

A portable water purifying apparatus for treating contaminated water to provide drinking water solely from the passage of said contaminated water through said apparatus comprising an elongated tube having a diameter of a size as to allow suction to be applied by a user's mouth, said tube having an interior conduit connecting an upper outlet and a lower inlet, said conduit having successive adjacent sections from said inlet and said outlet, a first section containing a primary filter means for removing particulate matter, a second section containing a halogenated ion exchange resin for removing harmful bacteria, viruses and the like, a third section containing a secondary filtration material for removing additional particulate material, a fourth section containing activated carbon granules for removing undesirable odors, tastes and hydrocarbons, and a fifth section containing a secondary filter means for removing substantially all remaining particulate matter, whereby on the application of said suction when said lower inlet is inserted into a source of contaminated water, said contaminated water is treated to permit the ingestion of water directed from said upper outlet.
